Which instruments will become inoperative if the pitot tube becomes clogged?

Airspeed

Which instruments will become inoperative if the static vents become clogged?

Airspeed, altimeter, and vertical speed.

If the pitot tube and outside static vents become clogged, which instruments would be effected?

The altimeter , airspeed, and vertical speed indicator.

Which V-speed represents maneuvering speed?

VA

What does the red line on an airspeed indicator represent?

Never-exceed speed.

Which color identifies the never-exceed speed?

Red Radial Line

Which color identifies the power-off stalling speed in a specified configuration?

Lower limit of the green arc.

Which would provide the greatest gain in altitude in the shortest distance climb after takeoff?

VX

After takeoff, which airspeed would be the pilot use to gain the most altitude in a given period of time?

VY

Which color identifies the normal flap operating range?

The white arc.

Which color identifies the power-off stalling speed with wing flaps and landing gear in the landing configuration?

The lower limit of the white arc.

What is an important airspeed limitation that is not color coded on airspeed indicators?

Maneuvering speed.

Which V-speed represents maximum flap extended speed?

VFE

Which V-speed represents maximum landing gear extended speed?

VLE

VSO is defined as the

stalling speed or minimum steady flight speed in the landing configuration.

If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter?

The elevation of the departure area.

At what altitude shall the altimeter be set to 29.92, when climbing to cruising flight level?

18,000 feet MSL

Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates

true altitude at field level.

How do variations in temperature affect the altimeter?

Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.

What is true altitude?

The vertical distance of the aircraft above sea level.

Under what conditions will true altitude be lower than indicated altitude?

In colder than standard air temperature.

What is absolute altitude?

the vertical distance of the aircraft above the surface.

What is density altitude?

The pressure altitude corrected for nonstandard temperature.

What is pressure altitude?

The altitude indicated when the barometric pressure scale is set to 29.92.

Under what condition is indicated altitude the same as true altitude?

When at sea level under standard conditions.

If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs?

700-foot increase in indicated altitude

Under which condition will pressure altitude be equal to true altitude?

When standard atmospheric pressure conditions exist.

Under what condition is pressure altitude and density altitude the same value?

At standard temperature.

If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting being adjusted, the altimeter will indicate

lower than the actual altitude above sea level.

If a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate

higher than the actual altitude above sea level.

Which condition would cause the altimeter to indicate a lower altitude than true altitude?

Air temperature warmer than standard.

How should a pilot determine the direction of bank form an altitude indicator?

By the relationship of the miniature airplane to the deflected horizon bar.

A turn coordinator provides an indication of

movement of the aircraft about the yaw and roll axis.

To receive accurate indications during flight from a heading indicator, the instrument must be

periodically realigned with the magnetic compass as the gyro precesses.

Deviation in a magnetic compass is caused by the

magnetic field within the aircraft distorting the lines of magnetic force.

The angular difference between true north and magnetic north is

magnetic variation.

In the northern hemisphere, a magnetic compass will normally indicate a turn towards the north if

an aircraft is accelerated on an east or west heading.

In the northern hemisphere, the magnetic compass will normally indicate a turn toward the south when

the aircraft is decelerated while on an east-west heading.

What should be the indication on the magnetic compass as you roll into a standard rate turn to the right from a south heading in the northern hemisphere?

The compass will indicate a turn to the right, but at a faster rate than is actually occurring.

In the northern hemisphere, a magnetic compass will normally indicate initially a turn toward the west if

a right turn is entered from a north heading.

During flight, when are the indications of a magnetic compass accurate?

Only in straight-and-level unaccelerated flight.
